Following this announcement we upgraded the Node version on our internal services and on all the projects; if your package.json forcefully specifies an unpatched version, you’re strongly encouraged of updating it. We suggest the following:

"engines": {
"node": "8.x"
},

but you can also use 7.x, 6.x (current LTS) or 4.x. This way you will be sure to always use the latest release with all the patches.
